The French inventor Joseph-Marie Jacquard , in designing an automatic loom, used thin, perforated wooden boards to control the weaving of complicated designs. During the 1880s the American statistician Herman Hollerith conceived the idea of using perforated cards, similar to Jacquard’s boards, for processing data. Employing a system that passed punched cards over electrical contacts, he was able to compile statistical information for the 1890 United States census.

计算机英语实用教程第三版课后练习题含答案
计算机英语实用教程第三版课后练习题含答案第一章练习题答案1. What is the difference between a CPU and a GPU?A CPU (Central Processing Unit) is a general-purpose processor that performs tasks that require complex arithmetic and logical operations. A GPU (Graphics Processing Unit), on the other hand, is a specialized processor that is designed to handle tasks that involve highly parallelizable computations, such as those required for rendering graphics.2. What is the difference between RAM and ROM?RAM (Random Access Memory) is a type of memory that stores data temporarily while the computer is running. RAM is volatile, meaning that its contents are erased when the computer is turned off. ROM (Read-Only Memory), on the other hand, is a type of memory that stores data permanently, even when the computer is turned off. ROM is non-volatile, meaning that its contents are retned even when there is no power.3. What is the difference between a bit and a byte?A bit is the smallest unit of digital information, represented by a binary digit (0 or 1). A byte, on the other hand, is a unit of digital information that consists of eight bits. Bytes are commonly used to represent characters, such as letters and numbers.4. What is the purpose of an operating system?An operating system (OS) is a software program that manages the resources of a computer, including the CPU, memory, storage, and devices such as printers and displays. The purpose of an operating system is to provide an environment in which applications can run and interact with the hardware without directly accessing the underlying hardware.5. What is the difference between a compiler and an interpreter?A compiler is a program that translates the source code of a program into executable code that can be run on a specific computer platform. The resulting executable code can be run multiple times without the need for recompilation. An interpreter, on the other hand, is a program that reads and executes source code instructions one at a time. Interpreted code is typically slower than compiled code, but does not require the extra step of compilation before it can be run.第二章练习题答案1. What is the difference between a LAN and a WAN?A LAN (Local Area Network) is a network that connects computers and other devices that are located in the same physical location, such as an office building or a home. A WAN (Wide Area Network), on the other hand, is a network that connects computers and other devices that are located in different physical locations, often separated by vast distances.2. What is a router and how does it work?A router is a device that connects two or more networks together and forwards data between them. Routers use routing tables to determine thebest path for data to take between networks, and use protocols such as TCP/IP to communicate with other devices on the network.3. What is the difference between TCP and UDP?TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols used for transmitting data over the internet. TCP is a connection-oriented protocol, which means that it establishes avirtual circuit between two endpoints over which data can be transmitted. TCP uses error correction and flow control to ensure that data arrivesat its destination correctly and in the correct order. UDP, on the other hand, is a connectionless protocol that does not establish a virtual circuit between endpoints. UDP does not provide error correction or flow control, but is often used in situations where speed and simplicity are more important than reliability.4. What is a DNS server?A DNS (Domn Name System) server is a special type of server that translates domn names into IP addresses. When a user enters a domn name into their web browser, the browser sends a request to a DNS server to find the corresponding IP address for that domn name. The DNS serverthen returns the IP address to the browser, which can then connect tothe website.5. What is a firewall and how does it work?A firewall is a security device that is used to protect a networkfrom unauthorized access. Firewalls can be implemented as hardware or software, and typically work by examining incoming and outgoing network traffic and blocking any traffic that does not meet a set of predefinedrules. Firewalls can be configured to block specific types of traffic, such as traffic from certn IP addresses or traffic that uses a certn protocol. Firewalls can also be configured to allow or deny access to specific network resources based on user or device credentials.。

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:Computers can communicate with other computers through a series of connections and associated hardware called a network. The advantage of a network is that data can be exchanged rapidly, and software and hardware resources, such as hard-disk space or printers, can be shared. Networks also allow remote use of a computer by a user who cannot physically access the computer.One type of network, a local area network (LAN), consists of several PCs or workstations connected to a special computer called a server, often within the same building or office complex. The server stores and manages programs and data. A server often contains all of a networked group’s data and enables LAN workstations or PCs to be set up without largestorage capabilities. In this scenario (方案), each PC may have “local”memory (for example, a hard drive) specific to itself, but the bulk of storage resides on the server. This reduces the cost of the workstation or PC because less expensive computers can be purchased, and it simplifies the maintenance of software because the software resides only on the server rather than on each individual workstation or PC.IV.

在计算机科学中，操作系统是控制计算机的基本软件。
它具有三个主要功能：协调和操纵计算机硬件，如计算机内存、打印机、磁盘、键盘、鼠标和监视器；组织各种存储介质上的文件，如软盘、硬盘、光盘（CD）、数字视盘（DVD）和磁带以及管理硬件错误和数据丢失。
在以掌上电脑和电子游戏机为典型代表的一些计算机中，整个操作系统小到可存储在只读存储器（ROM）中。
对几乎所有的个人电脑、服务器、工作站、大型机以及超级计算机而言，操作系统程序相当大，因此大部分存储在硬盘上。
操作系统的小型引导程序存储在只读存储器上，并在系统启动时提供必要的指令，用于将操作系统的核心装入内存。
操作系统的这个核心部分称为内核，它提供最基本的操作系统服务，如内存管理和文件存取。
在计算机运行的整个时间内，内核一直驻留在内存中。
操作系统的其他部分，如定制实用程序，需要时才装入内存。
二、操作系统如何工作操作系统控制不同的计算机进程，如运行电子表格程序或从计算机内存中存取信息。
一个重要的进程是解释命令，使得用户可以和计算机通信。
一些命令解释器是面向文本的，需要键入命令或通过键盘上的功能键选择命令。
另一些命令解释器使用图形，并允许用户通过指点图标进行通信。
图标是屏幕上的图片，代表特定的命令。
初学者一般会发现面向图形的解释器比较容易使用，但许多有经验的计算机用户更喜欢面向文本的命令解释器，因为它们功能更强。
操作系统可以是单任务的，也可以是多任务的。
较早的单任务操作系统每次只能运行一个进程。
例如，计算机打印文档时，直到打印结束才能开始另外一个进程或响应新的命令。
所有的现代操作系统都是多任务的，可以同时运行数个进程。
然而，在大多数计算机中仅有一个中央处理器（计算机的计算和控制单元），因此多任务操作系统制造了数个进程同时在一个中央处理器上运行的错觉。
制造这种错觉最常用的机制是分时段的多任务处理，靠这种方法每个进程单独运行一段固定的时间。
如果一个进程在分配的时间内没有完成，它就暂停，让另外一个进程运行。

Fill in each of the blanks with one of the words given in the following list, makingchanges if necessary:Data communications is the process of transmitting and receiving data in an orderly wayso the data that arrives at its destination is an accurate duplication (复制) of the data that was sent. When data travels a short distance, such as when you send data from your computer to your printer, it is referred to as local communications. When data travels a long distance, thecommunication is referred to as telecommunications; the prefix (前缀) “tele” is derived from aGreek word that mean s “far” or “far off.”The difference between a short distance and a long distance is somewhat arbitrary (武断的). For example, if your computer sends data to a printer in the next room, it is regarded as local communications; if you phone the person in the next room, you are transmitting data over a telecommunications device. However, the same basic communications concepts apply to both local communications and telecommunications.Basic data communications concepts are the building blocks for understanding how datatravels on a communications system. These concepts come in handy (派得上用处) when you install, configure, or upgrade a local area network. In addition, these concepts help you set up modems, fax machines, and cellular data transfers.IV. Translate the following passage from English into Chinese: 个人计算机使用电信来提供传输链路，用于传送音频、视频、文本、软件和多媒体服务。

Fill in each of the blanks with one of the words given in the following list, makingchanges if necessary:CD-ROM stands for compact disc read-only memory. Unlike floppy and hard disks,which use magnetic charges to represent 1s and 0s, optical discs use reflected light. On aCD-ROM disc, 1s and 0s are represented by flat areas and bumpy (高低不平的) areas (called“pits”) on its bottom surface. The CD-ROM disc is read by a laser that projects a tiny beam oflight on these areas. The amount of reflected light determines whether the area represents a 1or a 0.Like a commercial CD found in music stores, a CD-ROM is a “read-only” disc.Read-only means it cannot be written on or erased by the user. Thus, you as a user haveaccess only to the data imprinted (压印) by the publisher.A single CD-ROM disc can store 650 megabytes (兆字节) of data. That is equivalent to451 floppy disks. With that much information on a single disc, the time to retrieve or accessthe information is very important. An important characteristic of CD-ROM drives is theiraccess rate.IV.
